• AJAX - PHP - FFMPEG - Execution not completing

  6 septembre 2018, par Hue Man

  Here is a slightly tricky situation :

  I am using ajax to call a function that uses FFMpeg to convert a video.

  The code all works fine EXCEPT :

  The execution is cut short so I end up with a video of 2 frames.

  I assume this is ajax causing the problem because as far as its concerned, its called the function and returned a success output to my php page.

  In other words, the ffmpeg script cuts off when the ajax has completed.

  Is there a way I can tell ajax to wait for the ffmpeg function to finish or do i need to set up a cron job for it to run in the background ?

  EDIT :

  Heres the code :

  AJAX :

  // watermark($thevideo)
  
  var ajaxurl = "<?php echo admin_url('admin-ajax.php'); ?>";
  
  var formData = new FormData();
  
  
  
  formData.append('thevideo', thevideo);
  
  formData.append('action', "watermark");
  
  
  
  $.ajax({
  
  url: ajaxurl,
  
  type: "POST",
  
  data:formData,cache: false,
  
  processData: false, // Don't process the files
  
  contentType: false, // Set content type to false as jQuery will tell the server its a query string request
  
  success:function(data) {
  
      alert(data);
  
  }
  
  
  
  });

  PHP FFMPEG Function :

  // Watermark ***************
  
  // IMPORTANT!
  
  // This action & function can be called by ajax but requires absolute file paths!
  
  
  
  add_action( 'wp_ajax_watermark', 'do_watermark' );
  
  add_action( 'wp_ajax_nopriv_watermark', 'do_watermark' );
  
  
  
  function getabspath( $file_url ){
  
     return realpath($_SERVER['DOCUMENT_ROOT'] . parse_url( $file_url, PHP_URL_PATH ));
  
  }
  
  
  
  function do_watermark() {
  
  
  
      session_start();   
  
      ini_set('display_errors', 1);
  
      error_reporting(E_ALL);
  
  
  
  //  $thevideo = $_POST['thevideo'];
  
      $thevideo = getabspath($_POST['thevideo']);
  
  
  
      $newvideo = getabspath('./wp-content/uploads') . '/test.mp4';
  
  
  
      $thewatermark = getabspath('./wp-content/uploads/mefbpic.png');
  
  //  For some reason we have to OMIT THE DRIVE LETTER from the watermark image path
  
  //  AND the backslashes need to be turned forward even tho its an absolute path!?!
  
      $thewatermark = substr($thewatermark,2); // Cuts off the first 2 chars. - (C:)
  
      $thewatermark = str_replace('\\','/',$thewatermark);
  
  
  
  //  require_once('./vendor/autoload.php');
  
      require_once(getabspath('./vendor/autoload.php'));
  
  
  
  $ffmpeg = FFMpeg\FFMpeg::create(array(
  
  'ffmpeg.binaries' => getabspath('./FFMpeg/bin/ffmpeg.exe'),
  
  'ffprobe.binaries' => getabspath('./FFMpeg/bin/ffprobe.exe'),
  
  'timeout' => 3600, // The timeout for the underlying process
  
  'ffmpeg.threads' => 12, // The number of threads that FFMpeg should use
  
  ));
  
  
  
      $video = $ffmpeg->open($thevideo);
  
  
  
      $video
  
        ->filters()
  
        ->resize(new \FFMpeg\Coordinate\Dimension(640, 360))
  
        ->watermark($thewatermark, [
  
          'position' => 'relative',
  
          'bottom' => 50,
  
          'right' => 50,
  
        ])
  
        ->synchronize();
  
      //$video
  
      //  ->save(new \FFMpeg\Format\Video\X264(), $thevideo);
  
  
  
          $format = new \FFMpeg\Format\Video\X264();
  
          $format->setAdditionalParameters(array('-y'));
  
          $video->save($format, $newvideo);
  
  
  
      echo 'done!';
  
  
  
  }

• FFMpeg\Exception\RuntimeException Encoding failed - Laravel 4 PHP-FFMPEG

  10 avril 2014, par Woogygun

  I'm using PHP-FFMPEG and the latest version of FFPMEG this is the same for my localhost and production server. Im encoding a .wav file(1.5 meg 44.1khz) to .mp3 128k bit rate.

  On localhost it runs without issues but, on the production server it gives the following error.

  FFMpeg \ Exception \ RuntimeException
  Encoding failed

  My binaries are located in the public folder right now for dev purposes.

  My code is as follows :

      Route::get('/audio', function() {
  
  $ffmpeg = FFMpeg\FFMpeg::create([
  
                                   'ffmpeg.binaries' => 'ffmpeg',
  
                                   'ffprobe.binaries' => 'ffprobe',
  
                                   'timeout'          => 3600]);
  
  $audio = $ffmpeg->open(public_path('track.wav'));
  
  $format = new FFMpeg\Format\Audio\Mp3();
  
  $format->on('progress', function ($audio, $format, $percentage) {
  
      echo "$percentage % transcoded";
  
  });
  
  $format-> setAudioKiloBitrate(128);
  
  
  
  $audio->save($format, 'track.mp3');

  }) ;

  I can also confirm that FFMPEG is running via shell access :

  myuser@mydomain.com [~/public_html/hidden/public]# ffmpeg -i track.wav file.mp3
